I think I'm more impressed by the fact that this TrendNet USB device apparently comes with software which allows it to work on a Mac. Claiming it is a "dual-band" 802.11n client strikes as a bit of marketing hype. Technically I believe my Early 2008 white Intel MacBook 4,1 (MB403LL/A) could also be claimed to be "dual band" since it can use either the 2.4GHz or the 5GHz band. (It's either one or the other at a time, of course. I don't know of *any* client that supports simultaneous dual-band. Given how few people would have any use for that capability, it's probably cheaper just to buy two dongle's (or whatever) than to try to build that sort of thing into a single piece of client hardware.) An indirect way of determining whether or not an 802.11n wireless client is dual band is to look at the specs and find out which protocols it supports in addition to 80211.n. If it also supports 802.11a then the client can work in the 5GHz band as well as 2.4GHz and so could be referred to as "dual-band". I don't think this terminology is commonly used with clients, but then WTHDIK? At least that's how I understand it ... -irrational john -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
